1.  Verify Your First Backup
=====================================================
When you make your first backup with Conner Backup Exec, it
is highly recommended that you use the Compare After Backup 
option. During the Compare phase, Conner Backup Exec compares 
each file on the tape with the original on your hard drive to 
ensure that they are identical. While comparing will increase 
the time of the backup, it will confirm that your computer 
system, tape drive, and Conner Backup Exec are working 
together correctly. If compare fails, run a hard disk utility 
program to determine whether the hard drive is free of errors 
and try the backup again.



2.  Before You Run Your First Scheduled Backup
=====================================================
Before you run your first scheduled backup, you should run
a short backup with Compare After Backup selected (see above). 
When the window advising you to not use your floppy drives
during backup appears, select "Disable This Message." This
will allow your scheduled backup to proceed uninterrupted.


3.  Tape Format Incompatibilities
=====================================================
Because of inconsistencies in the formatting process used by
different tape drives, it is highly recommended that you
format QIC tapes in the drive where you will use them.

NOTE: Conner Backup Exec cannot format AccuTrak tapes. If 
your drive supports AccuTrak tapes, you should purchase them 
preformatted.


4.  Installing Conner Backup Exec After Other Backup Programs
=====================================================
You may experience difficulty running Conner Backup Exec 
if some device files from other backup programs are 
found in your SYSTEM.INI file. If you can't start 
Conner Backup Exec, try commenting the following devices out 
of your SYSTEM.INI file:

    CMSWTAPE.386
    CMSDTAPE.386
    CPVBX.386
    FASTBACK.386
    IRW286.DRV
    VIRWT.386
    VITD.386

To do this:

  1. Open the SYSTEM.INI file using a text editor.
  2. Search for the device name(s), e.g., DEVICE=CPVBX.386
  3. Type a semicolon (;) at the beginning of the line.   


5.  Installing MS-DOS 6.x After Conner Backup Exec For Windows
=====================================================
MS-DOS 6.x installs an older version of the VFINTD.386 into the
DOS directory and then modifies the SYSTEM.INI
(DEVICE=C:\DOS\VFINTD.386). If you install MS-DOS 6.x after
Conner Backup Exec 2.0, the next time you launch Conner Backup Exec you
will be sent a warning dialog. This dialog notifies you that
the VFINTD.386 is the incorrect version. If you click OK in
this dialog Conner Backup Exec will save the existing SYSTEM.INI as
SYSTEM.QBW and make the necessary change to the "Device=" line
in the SYSTEM.INI. You can also make the changes manually by
performing the following steps:

  1. Open the SYSTEM.INI file using a text editor.
  2. Search for the VFINTD line (DEVICE=C:\DOS\VFINTD.386).
  3. Change the line to: DEVICE = [qbwin install path]\VFINTD.386.


6.  Setup Disk Space Estimates
=====================================================
To insure that the user always has enough disk space to
install Conner Backup Exec, the Setup program displays the
maximum amount of space that may be required for installation.
This estimate is affected by the actual options selected
for install and also includes some space that is necessary
in order to run the setup program.


7.  Compressed Drives
=====================================================
If you are using compression software such as Stacker or
DoubleSpace, do not back up the compressed file (for example,
stacvol.* or the dblspace files), back up the logical drive
instead. Because these compressed files are typically very
large, attempting to restore may cause problems if you do not
have enough disk space to restore the compressed file.


8.  Troubleshooting High-Speed Controllers
=====================================================
To properly set up your system, you should avoid using an
interrupt request (IRQ) that is used by another device 
(i.e., mouse, sound card, network card, scanner, etc.).
Some common IRQs that may already be used in your 
system include:

    IRQ 3     COM 2, 4 ports
    IRQ 4     COM 1, 3 ports

Symptoms of an IRQ conflict include Conner Backup Exec not
finding the tape controller and network problems when
backing up to tape.

IRQ usage can be determined by using the Microsoft Diagnostics
Program. Exit Windows and type MSD at the DOS prompt.


9.   Laptop/Notebook Video Conflicts
=====================================================
Some laptop and notebook computers may have video conflicts
that cause the tape drive to move the tape back and forth 
excessively  ("shoe-shining"). 

If you experience this, minimize the Conner Backup Exec icon, 
make the Program Manager window active, and move it over 
the top of the icon while the program is writing to or reading 
from the tape. The Conner Backup Exec window will activate itself 
when the backup or restore is finished, and this action should 
speed up your session.


10.  Laptop Power Management Conflicts
=====================================================
Some laptop power management systems take a "snapshot" of RAM and 
store it on the hard drive when they power down. This may create
a conflict if it occurs during a backup or restore or a tape 
formatting operation.

When using Conner Backup Exec, it is recommended that you turn
OFF all power management features and plug your laptop into an 
outlet rather than using the battery.


11.  Hardware Compression Not Supported
=====================================================
Conner Backup Exec for Windows does not support the
hardware compression function found on some high-speed
controller cards.


12.  Installing With Third-Party Windows Shells
=====================================================
If you use a third-party Windows shell program such as PCTools 
or Norton Desktop for Windows, Conner Backup Exec may
not install correctly. If you experience difficulty installing 
Conner Backup Exec under a shell, temporarily change your Windows shell
to the Program Manager before starting the setup program. To
change to the Program Manager, open your SYSTEM.INI file,
type a semicolon (;) in front of your current SHELL command in the
[boot] section, then type SHELL=PROGMAN.EXE on the following line.
For this change to take effect, you must restart Windows. Remove 
these changes after installation to restore your previous configuration.


13.  Parallel Port Drive Configuration
=====================================================
If your parallel port tape drive does not automatically 
configure, first ensure that the power to the drive is on. If 
it is, turn it off, then on, and try configuring it again. See 
below for more suggestions.


14.  Maximum Parallel Port Cable Length
=====================================================
Your parallel port tape drive should be connected directly to 
your system's parallel port. If you use the pass-through 
connector on the drive to connect a second device such as a 
printer, the maximum cable length for both devices is 
approximately 10 feet (3 meters). 

If you have difficulty using your tape drive when a second
device is connected to the pass-through connector, disconnect 
the second device and its cable while using the tape drive.

If you experience data loss when using a printer connected to 
the pass-through connector, shorten the printer's cable if 
possible or disconnect the tape drive while printing.


15.  Parallel Port Drive IRQ Conflict With Sound Cards
=====================================================
You may experience a conflict in IRQ selection if you are 
configuring a parallel port tape drive on a system that 
includes a sound card or built-in sound system. SoundBlaster 
cards and compatibles use a default IRQ of 7, which is 
also used by LPT1. If this conflict occurs, you can:

    *  Change your sound card's IRQ if possible. Some cards do 
       not allow this change and some games may not work 
       correctly.

    *  Reconfigure your parallel port to LPT2, which uses IRQ 
       5. See your system documentation for more information.


16.  Potential Conflict with Screen Savers
=====================================================
If you attempt to use Conner Backup Exec while a screen 
saver is active and you get DMA or other errors, manually 
disable the screen saver before running Conner Backup Exec.


17.  Encrypted Backup Sets
=====================================================
Conner Backup Exec cannot restore backup sets encrypted by 
other backup programs. You must use the original software to
restore them.


18.  Backing Up Large Numbers of Files to AccuTrak Tapes 
=====================================================
When using AccuTrak tapes, backing up a very large number of 
files--approximately 30,000 to an 80MB tape or 45,000 to a 
120MB tape--will result in an error. Divide the files into 
two or more backup sets and back up each set to its own tape.


19.  NetWare Server Information and AccuTrak tapes
=====================================================
Because of the proprietary format used by the tapes, NetWare 
bindery files, trustees, and extended attributes cannot 
be backed up to AccuTrak tapes.


20.  NetWare Files With an Execute Only (X) Attribute
=====================================================
NetWare files with an execute only (X) attribute will not be 
backed up, compared, or overwritten during a restore.


21.  Microsoft Works Thesaurus Corruption
=====================================================
The Microsoft Works Thesaurus requires that the archive bit (A)
be set. If you back up the Thesaurus, it may not work correctly. 
If this occurs, contact Microsoft Technical Support.


22.  Files Not Backed Up by Conner Backup Exec
=====================================================
Conner Backup Exec does not log or back up a number of files 
to avoid potential system conflicts if they are restored. 

  Compressed Volume files:

     DBLSPACE.0??
     DBLSPACE.BIN
     STACVOL.*
NOTE:  See section 7 above for more information about 
compressed drives.

  Windows swap files:

     386SPART.PAR
     WIN386.SWP

  NetWare System files:

     BACKOUT.TTS
     NET$SPL.QUE
     NET$MSG.SYS
     DIRSTAMP.SYS
     NET$OBJ.SYS*
     NET$PROP.SYS*
     NET$VAL.SYS*
     NET$BIND.SYS*
     NET$BVAL.SYS*
     SYS$LOG.ERR

* These NetWare bindery files will be backed up or restored only 
if you are logged on to a server as Supervisor. See your User Guide 
for more information.

Additionally, Conner Backup Exec will not back up a number of 
temporary files used by the program when these files are found 
in the program's directory.


23.  Formatting Tapes on 386 Machines 
=====================================================
If you encounter difficulties formatting tapes on a slower 386 
machine or receive a message stating "The tape controller is not
responding correctly.", make sure your turbo switch is on.


24.  Changes to SYSTEM.INI and WIN.INI
=====================================================
The following lines are added during installation:

WIN.INI [Extensions]
    set=[qbwin install path]\qbwin.exe^set

SYSTEM.INI [386enh]
    device=[qbwin install path]\vfintd.386

If the Load With Windows checkbox in the Backup Scheduler is 
checked, the following item is added to WIN.INI [Windows] load= 
line:

    load=[qbwin install path]\scheduler.exe

This item is removed from the load= line when the checkbox is 
unchecked and the Backup Scheduler is closed.


25.  Using Removable Media Drives
=====================================================
For your backup software to recognize and use a removable media 
drive such as a Bernoulli drive, the drive must be locked.
